i have a cisco switch 2950 and i have gone crazy trying to change the speed of some access ports. For example, when i type show interfaces fastethernet 0/3, it shows me the speed Auto-duplex, Auto-speed.

Then, i type interface fastethernet 0/3

speed 100

duplex full

and the port stay auto-duplex. the fastethernet 0/1 and 0/2 ports are full duplex/100 mbps and i do not even want to touch them. i have try many different ways and i can not accomplish it. i remove port security and still dont work.
